When I tried to increase max_intersections in 3.7 I got a parse error.
"Nonic03_Fail04X_.pov" line 10: Parse Error: No matching } in 
'global_settings', float function 'float constant' found instead

global_settings {
     adc_bailout       0.001
     ambient_light     rgb <1.000,1.000,1.000>
     assumed_gamma     2.200
     irid_wavelength   rgb <0.250,0.180,0.140>
     max_intersections 64
     max_trace_level   150
     number_of_waves   10
     noise_generator   3
     charset           ascii
}


Am I missing something?

It's a bug, not a feature :-/

According to the POV-Ray source code, "max_intersections FLOAT" is 
apparently supposed to do nothing in POV-Ray 3.7, but the parser fails 
to eat the FLOAT parameter.

You can work around this by commenting-out the offending line (or 
placing a "#if (version < 3.7)...#end" around it). Actually, you should 
also have received a parser warning, "'max_intersections' is no longer 
needed and has no effect in POV-Ray 3.7 or later."

Oh! did I miss out that it had a #version 3.6; before the Global 
Settings block?

Then it is feature that I did not get the warning with #version 3.6; but 
do with #version 3.7; :-P



scene that has a few reflections and refractions. It has been confirmed 
by StephenS.
What sort of dump do you want with the scene file?

Yes, that's intentional indeed :-)

Dunno, I think Chris knows how to analyze Windows "core dumps". I 
personally prefer to re-create the error and single-step around the code.

Well I'll Start a new thread and upload the scene file in 
povray.beta-test.binaries as it needs an imagemap for it to fail.
